Hastelloy G-30 Seamless Pipe & Tube Supplier

As a professional nickel alloy supplier, we supply high-performance Hastelloy G-30 seamless pipe & tube.
Hastelloy G-30 seamless pipe & tube are a high-performance nickel-based alloy material with excellent corrosion resistance and high-temperature stability. They are widely used in chemical, petroleum, energy and environmental protection fields. The alloy performs well in strong acid, strong oxidizing media and complex corrosive environments, especially in phosphoric acid, sulfuric acid and mixed acid environments.
To ensure the quality of each Hastelloy G-30 seamless pipe & tube, we strictly implement hydrostatic testing and eddy current flaw detection. The hydrostatic test verifies the pressure bearing capacity and sealing of the pipe by applying water pressure higher than the working pressure to ensure no leakage or structural defects. Eddy current flaw detection uses the principle of electromagnetic induction to accurately detect defects such as tiny cracks and pores on the surface and near the surface of the pipe to ensure the integrity and safety of the material. The combination of these two key testing methods ensures the reliability and durability of the product and meets the high standards of industrial applications.

Chemical Composition of Hastelloy G-30

*Chemical Composition According to ASTM B622

The high chromium content significantly improves the oxidation resistance, while the addition of molybdenum and tungsten further enhances the material's resistance to pitting and crevice corrosion.
